Isolated bilateral molariform mandibular second premolars; a case report.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMolariform second premolar is a rare dental anomaly where the second premolar resembles a molar in size and shape. This condition is often linked to macrodontia, a rare enlargement of teeth that disrupts dental proportions and can manifest in isolated, relative, or generalized forms. Although mandibular second premolars are more prone to morphological variability, the occurrence of bilateral molariform premolars, induced by a unique form of gemination, is exceptionally uncommon and infrequently documented, thus making this case clinically significant. CASE PRESENTATION: This case report illustrates a rare bilateral presentation of molariform second premolars in the mandibular arch of a young patient. Both premolars displayed exaggerated mesiodistal dimensions, molar-like occlusal morphology with multiple cusps, and disproportionate faciolingual dimensions. Diagnosis was established through detailed clinical examination and radiographic evaluations. The report explores the treatment challenges posed by the enlarged tooth size and abnormal morphology, including their impact on orthodontic alignment and restorative planning. The patient was scheduled for reshaping of the macrodont premolars after finishing orthodontic treatment, which was planned for correction of overjet, overbite, as well the deep curve of spee.
conclusionsMolariform premolars, though uncommon, have a profound impact on dental alignment and treatment outcomes. Their morphological uniqueness might potentially be ignored; therefore, dental professionals should remain vigilant for such anomalies during routine examinations to prevent complications like crowding, malocclusion, and caries. Early diagnosis and strategic intervention are crucial for prevention and interdisciplinary management of unexpected complications during dental procedures. This case emphasizes the importance of routine examination and interdisciplinary collaboration in identifying and treating such anomalies.
